SEGIS Overview Introduction
“Accelerate” the wide-spread adoption of solar electric technologies across the United States
The mission of the US DOE’s Solar Program is to:
Market TransformationSystems Integration
Photovoltaics (PV)
Concentrating Solar Power (CSP)
Distributed Generationon-site or near point of use
Centralized Generationlarge users or utilities
DOESETP
Solar Energy Grid Integration Systems (SEGIS)
Captured the result of 3 industry workshops that identified and prioritized technical issues related to high penetration PV
Described the goals and requirements of the SEGIS program
Conveyed detailed program requirements to SEGIS solicitation bidders

ENABLE HIGHLY INTEGRATED,INNOVATIVE,
ADVANCED INVERTERS,CONTROLLERS,CRITICAL BOSCONCEPTS &
ENERGY MANAGEMENT FOR RESIDENTIALAND COMMERCIAL
PV APPLICATIONS
VISION NEEDSAll Non-module costs must be reduced. Brackets show magnitude of
improvement needed
Without dramatic non-module cost improvements, the goals ($.05-$.10/kWh
by 2015) will not be met even if PV modules are given away!
SEGIS = “VALUE ADDED”
6
SEGIS focus is to develop the intelligent hardware that interconnects PV to the evolving “Smarter” electrical grid
